I kinda feel stupid for bashing the one site. The 'http' mirror DOES work, but you can only use it once meaning if it messes up or you want to watch another, you have to wait a whole day. It also is pretty slow, I have high speed internet and it still probably took a good five to ten mintes to load. I dunno, maybe I'm just exaggerating...

The site's at:
http://www.animetheme.com/ff8/fmv.html

It also has a variety of other FF games too.
